Gravitational couplings of orientifold planes
We reanalyse the gravitational couplings of the perturbative orientifold planes Op, Op (and D-branes). We first compute their D−1 instantonic corrections for p = 3. Then, by using U-dualities, we obtain the Wess-Zumino terms of orientifolds with RR flux for p ≤ 5. The expressions for the effective actions can be partially checked via M-theory. We point out a previous oversimplification and we s...
متن کاملOff - shell Crosscap State and Orientifold Planes
We show that a non-trivial dilaton condensation alters the dimensions of orientifold planes. An off-shell crosscap state which naturally interpolates between the usual onshell crosscap states and their T-duals plays an important role in the analysis. We present an explicit representation of the off-shell crosscap state on an RP 2 worldsheet in the gauge in which the worldsheet curvature in the ...
متن کاملGravitational Couplings for Generalized Orientifold Planes
The result that this paper presents is about gravitational couplings for generalized orientifold planes. The usual orientifold planes do not have gauge fields on their worldvolumes. The generalized orientifold planes that this paper consider have SO(2k) Yang-Mills gauge fields-bundles over their corresponding worldvolumes. The aim of the present paper is to display the Wess-Zumino part of the e...
متن کاملOn the M-theory Interpretation of Orientifold Planes
We obtain an M–theory interpretation of different IIA orientifold planes by compactifying them on a circle and use a chain of dualities to get a new IIA limit of these objects using this circle as the eleventh dimension. Using the combination of the two IIA description, we give an interpretation for all orientifold four-planes in M-theory, including a mechanism for freezing M5branes at singular...
متن کاملAnomaly Inflow at Singularities
Many noncompact Type I orbifolds satisfy tadpole constraints yet are anomalous. We present a generalization of the anomaly inflow mechanism for some of these cases in six and four dimensions.
